Company Announced Acquisition of Cubist, Acquired Idenix and Divested
its Consumer Care Business

Targeted Cost Savings are on Track to be Realized by the End of 2015

January 12, 2015 07:00 AM Eastern Standard Time

KENILWORTH, N.J.--(BUSINESS WIRE)--Merck (NYSE:MRK), known as MSD outside the United States and Canada,
today will report on the ongoing execution of its multi-year, strategic
initiative to sharpen its commercial and research and development (R&D)
focus, redesign its operating model and reduce its cost base. In October
2013, Merck launched its global initiative
to transform the company into a more competitive and innovative company
and to build a platform for sustained future growth.

“Over the past 15 months, we’ve seen the results of our transformation
strategy, including advancing major pipeline candidates, completing
multiple business development actions and securing first-in-class
product approvals,” said Kenneth C. Frazier, chairman and chief
executive officer, Merck. “As a result of our strong and continued
commitment to the pursuit of science and R&D, our labs are focused on
many of the most innovative areas in biomedical research today, which we
believe is the best way to create intrinsic value for both society and
for our shareholders.”

Positioned for Long-Term Growth Through Innovation

As a result of prioritizing its research efforts in the core areas where
it can make the most impact on addressing critical areas of unmet
medical need, Merck is now focused on many of the world’s most urgent
global health challenges, including immuno-oncology, hepatitis C,
cardiometabolic disease, antimicrobial resistance and Alzheimer’s
disease. Merck accelerated several of its key clinical programs in 2014,
positioning the company for long-term growth.

In addition to being the first anti-PD-1 therapy approved in the
United States, KEYTRUDA (pembrolizumab) received Breakthrough Therapy
Designation from the U.S. Food and Drug Administration (FDA) in two
tumor types: advanced melanoma and advanced non-small cell lung cancer
(NSCLC).

In mid-year 2015, Merck expects to submit a supplemental Biologics
License Application (sBLA) to the FDA for KEYTRUDA for the treatment
of patients with Epidermal Growth Factor Receptor (EGFR)
mutation-negative and Anaplastic Lymphoma Kinase (ALK)
rearrangement-negative NSCLC whose disease has progressed on or
following platinum-containing chemotherapy.

In 2014, Merck engaged in multiple research collaborations in
oncology, and data for KEYTRUDA was presented in seven different types
of cancer. KEYTRUDA continues to be studied in more than 30 cancers
and in 20 combination settings.

Merck also continued to accelerate its R&D efforts in its other core
areas of focus, such as hepatitis C.

The company expects to file a New Drug Application (NDA) with the FDA
in the first half of 2015 for grazoprevir/elbasvir (MK-5172/MK-8742),
the company’s investigational oral, once-daily combination regimen for
the treatment of chronic hepatitis C virus (HCV) infection.

As a result of the acquisition, the Phase 2 C-CREST studies (NCT02332707
and NCT02332720)
have been initiated to study combination regimens of grazoprevir and
MK-3682 (formerly IDX21437)with either elbasvir or
MK-8408 for the treatment of HCV infection.

In total, Merck now has more than 10 Phase 3 clinical programs in its
core therapeutic areas, as well as in other areas with significant
potential such as Alzheimer’s disease, and has multiple strategic
collaborations.

In addition to oncology collaborations, Merck also initiated several
other clinical research collaborations in 2014, such as working with
NewLink on the development of an investigational Ebola vaccine and a
cardiovascular-focused collaboration with Bayer.

Additionally, Merck has taken several steps to create and maximize near-
and longer-term commercial leadership opportunities that create value
for sustained growth.

The initial indication for KEYTRUDA was filed and launched in the
United States within five months in 2014; the company continues to
focus efforts on this priority launch. Additionally, filings are
underway in the European Union and globally for advanced melanoma.

Merck bolstered its product portfolio by entering into an agreement
to acquire Cubist Pharmaceuticals, a global leader in the discovery,
development and supply of antibiotics to treat serious and potentially
life-threatening infections.

Following the completion of the acquisition of Cubist in the first
quarter of 2015, Merck looks forward to launching ZERBAXA
(ceftolozan/tazobactam), a recently approved antibiotic to treat
Gram-negative bacteria, a key cause of in-hospital infections.

In total, Merck received approval for seven products in 2014, such as
GARDASIL 9 (Human Papillomavirus 9-valent Vaccine, Recombinant) and
BELSOMRA (suvorexant).

In 2014, the company’s redesigned operating model enabled Merck to
remain on track to meet its goal of realizing $2.5 billion in annual net
cost savings by the end of 2015. These savings are off of the company’s
full-year 2012 expense levels. As part of its prioritization efforts,
the company continued to review its assets to determine whether they
could provide the best short- and longer-term value with Merck or
elsewhere.

As a result, Merck divested its consumer
care business to Bayer for $14 billion, which provided capital to
the company to better resource its core areas of focus and return cash
to shareholders.

Merck determined its Animal Health business remains a key growth
driver and is committed to looking for ways to augment this critical
business.

In 2014, the company continued to streamline its physical footprint,
divesting multiple sites within its manufacturing network around the
world and completing the closures of facilities in Whitehouse Station
and Summit, N.J.
